Abstract (en)
An electric storage device (10) has an electrode laminate unit (12) including positive electrodes (14), negative electrodes (15) and a lithium electrode (16) provided at the outermost part of the electrode laminate unit (12). The lithium electrode (16) has a lithium-electrode current collector (26) welded to a negative-electrode current collector (22) and a lithium unit (27) sandwiched between a lithium-electrode current collector (26) and the negative electrode (15). The lithium unit (27) is composed of a lithium holding plate (27a) that is in contact with the lithium-electrode current collector (26), and a lithium ion source (27b) that is provided to the lithium holding plate (27a). The lithium ion source (27b) is not mounted on the lithium-electrode current collector (26), but only the lithium-electrode current collector (26) is laminated and welded, whereby any damage of the lithium ion source (27b) is prevented, and the manufacturing operation is simplified.
